void pointer and Casting

Code

#include <stdio.h>

void add_and_print(void *a, void *b, char type) {
    if (type == 'f') {
        float *a_f = (float *)a;
        float *b_f = (float *)b;
        printf("%.1f", *a_f + *b_f);
    } else if (type == 'i') {
        int *a_i = (int *)a;
        int *b_i = (int *)b;
        printf("%d", *a_i + *b_i);

    } else {
        printf("Unhandled add\n");
    }
    return;
}

int main() {
    char type;
    scanf(" %c", &type);

    if (type == 'i') {
        int x, y;
        scanf("%d %d", &x, &y);
        add_and_print(&x, &y, type);
    } else if (type == 'f') {
        float x, y;
        scanf("%f %f", &x, &y);
        add_and_print(&x, &y, type);
    }

    return 0;
